Drive Specifications
2.14 Environmental protection
Seagate designs its products to meet environmental protection requirements worldwide, including regulations restricting certain
chemical substances.
2.14.1
European Union Restriction of Hazardous Substances (RoHS) Directive
The European Union Restriction of Hazardous Substances (RoHS) Directive, restricts the presence of chemical substances, including
Lead, Cadmium, Mercury, Hexavalent Chromium, PBB and PBDE, in electronic products, effective July 2006. This drive is manufactured
with components and materials that comply with the RoHS Directive.
2.14.2
China Restriction of Hazardous Substances (RoHS) Directive
This product has an Environmental Protection Use Period (EPUP) of 20 years. The following table contains information
mandated by China's "Marking Requirements for Control of Pollution Caused by Electronic Information Products"
Standard.
"O" indicates the hazardous and toxic substance content of the part (at the homogeneous material level) is lower than the threshold
defined by the China RoHS MCV Standard.
"X" indicates the hazardous and toxic substance content of the part (at the homogeneous material level) is over the threshold defined by
the China RoHS MCV Standard.
2.15 Corrosive environment
Seagate electronic drive components pass accelerated corrosion testing equivalent to 10 years exposure to light industrial
environments containing sulfurous gases, chlorine and nitric oxide, classes G and H per ASTM B845. However, this accelerated testing
cannot duplicate every potential application environment. Users should use caution exposing any electronic components to
uncontrolled chemical pollutants and corrosive chemicals as electronic drive component reliability can be affected by the installation
environment. The silver, copper, nickel and gold films used in Seagate products are especially sensitive to the presence of sulfide,
chloride, and nitrate contaminants. Sulfur is found to be the most damaging. In addition, electronic components should never be
exposed to condensing water on the surface of the printed circuit board assembly (PCBA) or exposed to an ambient relative humidity
greater than 95%. Materials used in cabinet fabrication, such as vulcanized rubber, that can outgas corrosive compounds should be
minimized or eliminated. The useful life of any electronic equipment may be extended by replacing materials near circuitry with sulfide-
free alternatives.
